arthel: ago you well know, kim jong un missile test came on friday, a day after the senate approved a package of sanctions on north korea, russia and iran, a bill that the white house is saying the president is ready to sign. so aside from more sanctions, jason, more military maneuvers as you say, the military action is not necessarily the best to take and twitter lashing and further sanctions on china, what is president trump's best most forceful option at this point? >> it's a great question. i think one of the questions that he's unfolded goes to not just sanctions but targeted sanctions at specific entities that are performing the bulk of sort of money laundry for the north koreans. there's ten companies identified by our intelligence asset and they do the majority to the financial system. so if the president trump can explain that to the people and go after those, keep in mind, this is going to upset beijing. it's kind of a tricky balance.
